Patent CA-2261828-A1 (CA)
Title: Calibration technique
Inventor: ROONEY ALLEN J
IPC: G01R35/00
Filed: 1999-02-15
Abstract: An operational parameter of a first element is based on information about a second element, where the information is received by a means external to the first element, and where the information defines at least how one characteristic of the second element changes as a function of at least one variable parameter. For example, in an illustrative embodiment, an adjustment is made to the output power of an output stage of an radio transmitter based on information about how a transmit filter located in the signal path between the output stage and an antenna, where the information received from a remote memory, and where the information defines how the transfer function of the transmit filter varies as a function of temperature. Advantageously, whenever the second element (e.g. the transmit filter) is replaced and/or whenever there is a change in the variable parameter (e.g. the temperature) such that the manner in which the second element operates (e.g. its transfer function) would also change, the first element (e. g. the output stage) is able to use the information to adjust its own operational parameter (e. g. output power).

Title: Variable length register device
Inventor: SHIMURA NAOKI
IPC: G06F9/30
Filed: 1999-03-22
Abstract: It is an object of the invention to provide a variable length register device which can be used not only for assigning an address of a memory but also as a general register. A memory outputs an instruction to gain access to a variable length register. A decoder decodes the instruction supplied from the memory and composes discriminators for assigning the variable length register and used areas therein. The first selectors read data stored in the used areas, which are assigned in the specified variable length register, in accordance with the discriminators composed in the decoder, and coordinates the areas storing the data therein. An arithmetic logical unit carried out operations based on the data read from the first selectors . The second selector reads the data outputted from the arithmetic logical unit, and stores them in the variable length register coordinating the used areas.

Title: Separator for fuel cell, fuel cell incorporating the same, and method of production of the same
Inventor: YOSHIMURA JOJI
IPC: C23C28/00
Filed: 1999-05-04
Abstract: An inexpensive and corrosion resistant metal-made gas separator includes a base formed by joining formed stainless steel base sheets face to face. The base carries on each of opposite surfaces thereof a first coating layer formed by plating with tin. The base is also coated with a second coating layer of a thermal expansion graphite. When incorporated into a fuel cell, the separator contacts gas diffusion electrodes that are formed from a carbon material similar to the carbon material of the second coating layer, so that the contact resistance is reduced. The first coating layer is formed after a passive state coating is removed from the stainless steel surface, so that an increase in the internal resistance of the separator caused by the passive state coating is substantially prevented.

Title: Capacitive dielectric heating system
Inventor: WELLS JOHN HENRY
IPC: A23L5/10
Filed: 1999-06-18
Abstract: A food product is heated by maintaining the food product in an AC electrical field provided by an RF signal at an RF frequency that matches a Debye resonance frequency or frequencies of one or more components of the food product. As the food product warms, the frequency of the RF signal is automatically adjusted to track changes in the Debye resonance frequency, which shifts in frequency as the temperature rises. Individual regions of the food product can be heated, by the use of grid electrodes, at different rates to assure uniform warming or to achieve a particular desired warming pattern.

Abstract: A computer system includes a graphical user interface, which enables a user to create and update a database query in a simple manner. The interface displays logic conditions within nested graphical containers (e. g. boxes) representing nested boolean AND and OR expressions. Containers and conditions may be dragged around to modify the logic. New containers may be created within existing containers. New conditions may be created within existing containers, by selecting a condition type from a predetermined list of condition types, and then entering details specific to the selected type. The query is used to access the database, so as to identify a subset of records that satisfy the query, and to display those records to the user.

Title: Marine engine silencing apparatus and method
Inventor: DENIS MATTHEW E
IPC: F01N13/00
Filed: 1998-08-06
Abstract: An apparatus and method for silencing marine engines. In one embodiment, a separation chamber (100) receives a fluid mixture (22) of exhaust gas (16) and liquid coolant (10) and a dynamic separation member (e.g., 106 or 116) separates the exhaust gas (16) from the liquid coolant (10). In one aspect of the invention, a horizontal axial-flow silencer includes a separation plate, having at least one dynamic separator, horizontally positioned in the separation chamber (100). A dam (130) maintains the free surface of the fluid mixture (22) at or slightly above the separation plate at an engine speed within nominal operating range, and provides for the continuing passage of exhaust gas (16) through the liquid coolant (10). The separation plate employs inertial effects introduced by a series of vanes (107) that deflect the gas-coolant mixture upstream to separate the coolant with a greater inertia from the exhaust gas (16) with a lesser inertia. Alternatively, the separation plate may consist of a mesh pad (116) that employs frictional effects to achieve a similar result. The separate exhaust gas (110) is passed through a resonator tube or tubes (150) to further attenuate the acoustic energy of the gas.

Abstract: Pharmaceutical compositions in powder form are prepared by loading drugs solubilized in supercritical fluids on cross-linked polymers. The loading process is carried out by means of two steps. In the first step the supercritical fluid is saturated with the drug in suitable temperature and pressure conditions. In the second step the supercritical fluid containing the drug is contacted with the cross-linked polymer. Owing to its particular properties the supercritical fluid penetrates into the polymer and allows the drug to impregnate the polymer itself. After the removal of the fluid the drug remains in the polymer itself.
